Macmillan CEO John Sargent posted an open letter on Publishersmarketplace to tell the tale of Amazon flexing its muscles in a price dispute on ebook prices. This is no doubt instigated by Apple's more publisher friendly policy for the upcoming iPad.

Here is a part of the letter and the link to the full letter:

"This past Thursday I met with Amazon in Seattle. I gave them our proposal for new terms of sale for e books under the agency model which will become effective in early March. In addition, I told them they could stay with their old terms of sale, but that this would involve extensive and deep windowing of titles. By the time I arrived back in New York late yesterday afternoon they informed me that they were taking all our books off the Kindle site, and off Amazon. The books will continue to be available on Amazon.com through third parties."

"Under the agency model, we will sell the digital editions of our books to consumers through our retailers. Our retailers will act as our agents and will take a 30% commission (the standard split today for many digital media businesses). The price will be set the price for each book individually. Our plan is to price the digital edition of most adult trade books in a price range from $14.99 to $5.99. At first release, concurrent with a hardcover, most titles will be priced between $14.99 and $12.99. E books will almost always appear day on date with the physical edition. Pricing will be dynamic over time."

Amazon's Kindle Team has responded to the open letter from the CEO of Macmillan. Here is the response:

"Dear Customers:

Macmillan, one of the "big six" publishers, has clearly communicated to us that, regardless of our viewpoint, they are committed to switching to an agency model and charging $12.99 to $14.99 for e-book versions of bestsellers and most hardcover releases.

We have expressed our strong disagreement and the seriousness of our disagreement by temporarily ceasing the sale of all Macmillan titles. We want you to know that ultimately, however, we will have to capitulate and accept Macmillan's terms because Macmillan has a monopoly over their own titles, and we will want to offer them to you even at prices we believe are needlessly high for e-books. Amazon customers will at that point decide for themselves whether they believe it's reasonable to pay $14.99 for a bestselling e-book. We don't believe that all of the major publishers will take the same route as Macmillan. And we know for sure that many independent presses and self-published authors will see this as an opportunity to provide attractively priced e-books as an alternative.

Kindle is a business for Amazon, and it is also a mission. We never expected it to be easy!
